Historical volatility is the annualized standard deviation of an underlying's past returns, typically measured over rolling windows like 10, 20, 30, or 60 days. The SHLD 30 day historical volatility is one of the most widely watched readings because it balances responsiveness with stability. Comparing Global X Defense Tech ETF's HV to its implied volatility reveals the volatility risk premium — when IV sits well above HV, option sellers tend to have an edge; when HV runs hot relative to IV, buyers may be underpaying for movement.
The Global X Defense Tech ETF (SHLD) seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the Global X Defense Tech Index.
